P4 board PCI divider

I have no idea about P4 MB's PCI divider setting.
Are most P4 mobo has 1/5 divider if I have P4 running at 166 Mhz FSB or when 1/4 or 1/5 divider kick in?
 
ummm, 166 fsb?
i dont think anyone has hit that with a p4 yet.
PCI/AGP dividers will very amoung manufacturers and chipsets.

what board/chipset/manufacturer are you interested in?
 
Well, I don't know exactly which mobo to get neither.
Guess stay w/ AMD too long now...🙂

I was thinking trying out the P4 1.6a like everyone else, but I am NOT going to OC my HD or PCI devices. (yeap, even my Morgan Duron capable of 166FSB w/ extremely stable, but because mobo lack of 1/5 divider, I have it running at 133FSB)

Just say if I am the lucky one who has the 166fsb P4, which mobo has the 1/5 divider?
Becaues, I don't see the point Downclock my HD if my CPU only running at 150 w/ 1/5 divier enable.
(hope you get my point..🙁 )

Back to the subject.....which mobo has 1/5 divider at what FSB?
(I assume all P4 mobo has 1/4 divider at 133FSB?)

Also, if you can recommend any good mobo to get. (stability is more of the key, instead of extreme OC)
 
THUGS,

On hardforum.com, there are a number of people running 160MHz to 168MHz FSB. The P4B266 will apparently run stable up to 170FSB.

No, Intel mobos only have a 1/3 PCI and 2/3 AGP dividers. You are aware that the default FSB for the P4 is 100MHz (Quad pumped to give an effective 400MHz FSB), right? Just about all overclocking P4 mobos have a 1/4 PCI divider and a 1/2 AGP divider though. Even at 150MHz with a 1/4 PCI divider you are only running your PCI devides at 37MHz whcih is not that big of a deal. But ya, when you get to 166MHz FSB, I'd DEFINITELY want a 1/5 PCI divider. 😉
 
thanks. 🙂
would you happen to know which mobo rated most stable at 133FSB?
( oh...did I mention I am cheap? 😉 )
 
No, Intel mobos only have a 1/3 PCI and 2/3 AGP dividers.

I don't think that's correct, Jack. I believe the new Intel P4 boards have a 1/2 and 1/4 divider at 133MHz + FSB.

 
some boards actually allow you to lock the PCI/AGP clock at nominal levels. i'm pretty sure the Abit BD-7 supports this. the asus p4b266 might as well.
